FIREPROOF BUILDBNGL- CONSTRUCTION.

Specification of Letters Patent.

Patented June 4, 1907.

Application tiled Argust 20, 1906. Serial No. 331,266.

in Fireproof Building Construction, of which the following is aspecification.

My invention relates to certain new and useful improvements in iireproofbuilding constructions wherein a light and rigid metallic frame work isemployed for partitions,

furring, ceilings, floors, and other structures; and my inventionconsists, essentially, in forming the metal lathing or other sheet uponthe surface of which concrete, mortar, or other plastic material isspread or placed,

lwith loops adapted to receive the upright metal strips or studdingwhich form the support for the metal lathing or sheet, whereby one ofsaid parts is secured directly to thev other part without the employmentof additional or supplemental fastening means.

My invention further consists in the arrangement whereby successivesheets of metal lathing orother plates having the aforesaid-loops may beplaced in position by sliding them over the uprights or studding membersso that the latter will interlock with the loops, and then giving saiduprights or studding members a quarter turn toset them on edge relativeto the lathing or sheets whereby the loops are expanded to impart atension to the sheets or plates and to eliminate any looseness or slackwhich may be lpresent therein; at the same time the studding members oruprights are iirmly interlocke'd to the sheets or plates without the aidof` tying wires or other fastening devices, and a rigid metallic framework is formed which is useful t in the construction of fireproofpartitions, furring, floors, ceilings, ctc, and for such purposes asrequire a reinforce concrete construction.

My invention also consists of the parts and the constructions andcombinations of parts which I will hereinafter describe and claim.

In the accompanying drawings forming part of this specification, Figure1, is a perspective view of a portion of a partition emv bodying myinvention. Fig. 2, vis an enlarged view showing a portion of a lathingsheet and an upright engaging the same; Fig. 3, is a view similar toFig. 2, but showing the u right turned on edge. Fig. 4, is a detail sowing my invention applied to a floor thereto,

orl ceiling construction. Fig. 5, shows the invention applied to atubular structure.

The essential object yof the present invention is to simplify andthereby cheapen the construction of partitions, furring, ceilings,floors, etc., of fireproof or reinforced concrete structures bydispensing with the' necessity of the usual tying wires, clips, lugs andlike fastening means which have heretoforebeen usedfor securing themetallathing, or other sheet, to 'the-uprights or studding which forms theframe work of the partition or other structure.

To attain the aforesaid object, I` may use either the slitted orexpanded sheet comvmonly used in partition constructions as a supportfor the mortar or plastic outer covering, and wherein the slits orexpanded portions serve to admit the plastic material and allow for theformation of the keys for holding the plastic material on the sheet; orI .may luse a sheet that is without such slits or expanded portions,which is desirable in some lnstances, as for ceilings and floors.

In the drawings, I illustrate my improvement in connection with thesheets A which, in this instance, are slitted at a ,in the usual or anysuitable manner, the portions between l the slits being pressedoutwardly to open the slits for the reception of the mortar or plasticmaterial placed on or over the sheet.

In this art'as it is practiced to-day, the sheets A are secured touprights or studding consisting of parallel strips B having littleinherent rigidity in themselves but connected to eachother to form alight, though rigid, structure capable of supporting the sheets A andmortar or outer plastic covering thereof. Several methods are followedfor securingthe sheets to the studding or upright strips; for instance,wires are passed through the slits or openings in the sheets A andpassed around the uprights or studding and the ends twisted together;separate clips are used to embrace the sheets and uprights bendabletongues are formed on the-'uprights or studding and, when the sheet-isap lied the tongues are bent over the s eets to secure means, however,require in every instance of which I am aware, a separate operation andone that takes considerable time to perform, is often difficult ofoperation. Y

My improvement contemplates overcoming the'diificulties usuallyattending the tying rol them. These sheet attaching or fastening of thesheets to the uprights or studding, b providing the sheets with meanswhich rea ily interlock directly With the s tudding or uprights. v

. Whatever the character of metal sheet used, I slit said sheet atsuitable points a and offset the slitted portions to form the relativelylong open loops C which are arranged inline on the back surface thereof,so that successive sheets may be slid edgewise over the ends of theuprights or studding until the required height of partition or length ofstructure is formed when forming a artition or the like, the uprights orstuddping is now placed in'its proper position, and secured at thebottom and top in any Well known or`appropriate manner, as by slippinthe slotted spacing 'pieces over t e para el adjacent stri s, as at 10in Fig. 1', and a ri id frame wor is produced and the lathing s eets anduprights or studding are interl'ocked one to the other-and withoutseparate fastening.

means. Y

In some instances, I may make the strips for the studding relativelythin or flat' and they lie flatwiseagainst the lathing sheets when thelatter are iirst slid thereover, as before described and when the sheetsare thus fitted over the uprights or studding, the latter are turned aquarter circle, or at right angles to their first position, so that theystand on edge relative to sheets, as shown in Fig. 3,

and then are secured at the upper and lower ends to the iloor andceiling support as before described. In thus turning the uprights fromthe position flat against the sheets, Fig. 2, to one edgewise relativethereto, the up-y rights expand or open up the loops making the latterbind tightly against the edges of the uprights or studding; at the sametime a tension is a plied to the sheet and any looseness or slack)therein is taken up whereby the sheet furnishes a rigid support for theouter plastic coating.

The same improvement is adapted for floor and ceiling constructions inwhich case the lates or sheets A may serve as a centering or concrete,and the bars B engage thel Tubular structures, for columns and the,

like, may be formedby the same arrangement, as in Fig. 5,'Withoutdeparting from the spirit of my invention.

In Whatever form of structure and Whatever the character of metal sheetused, it is only necessary to provide said sheet with loops of sulicientsize to take in the uprights or bars which form the frame work of thepartition, furring, ceiling, floor, etc., so that the said uprights orbars will interlock with the loops and hold the sheets4 to the uprightswithout independent fastening means.

Having thus describedmy invention,what

I claim as new and desire to secure by Let;

ters Patent is,- l

l 1. The combination wi th a skeleton frame work composed of parallelbars or strips, of metallic lathing sheets having loops adapted to slipover said bars to thereby secure the -sheets directly .to the frame WorkWithout additional fastening means.

2. The combination with the upright members of a skeleton frame work, oflathing sheets having loops by which they may be slipped edgewise overthe ends of said meinber whereby the sheets and members are locked oneto the other without supplemental fastening means. 3. The combinationwith a vertical bar or stri of a metallic sheet having loops fixed to anoffset therefrom and extending in the direction of the length of thesheet. said loops adapted to receive said bar or strip and therebydirectly secure the sheet to thebar.

4. The combination with a bar or strip, having a greater -Width'thanthickness, of a lmetallic sheet having loops ollset from one side, saidsheet adapted to be slipped over the end of the bar so that the loopswill rcceive the bars latwise, and said bar adapted to be turnededgewise relative to the sheet whereby the loops are expanded and atonsion put upon intermediate parts of the sheet nesses.
